Different glasses sometimes have different color tint as well. I have three types; movie theater RealD type, and two Vizio styles..one stylish the other thicker. There is definitely a tint difference, some looking more blue the other more yellow. The difference is slight but its there. I end up using the thick rimmed utilitarian Vizio pairs, they give the best image to me. I too was looking into the more expensive types hoping for performance increases but the biggest performance increase is the reduction of crosstalk from going to a 240 Hz set from a 120.
